ET 66 - ET 66 M operator’s manual
DISPLAY MESSAGES
The machine is able to recognise various error states and machine statuses, which it
communicates to the operator by means of display messages.
Error messages
Err CAL Calibration error.
Run the calibration program.
Er3 CAL An error has been generated during execution of the calibration program.
Make sure you have fitted the correct standard weight and then repeat
the program.
Er4 CAL Attempt to calibrate the machine using a wheel with excess unbalance.
Balance the wheel (or at least reduce the unbalance) and repeat the
calibration program.
Err 7 The machine cannot currently activate the program requested.
Run a spin cycle and repeat the request.
Err 13 Attempt to perform calibration with incorrect wheel- machine distance.
Repeat calibration after fitting a spacer ring to alter the distance or use a
different wheel.
Err 28 Encoder error.
If this message appears frequently contact your service centre.
GO Err Acquisition of non-repetitive signals during a spin.
Make sure that the machine is resting properly on the floor and repeat
the spin taking care not to jolt the machine during signal acquisition.
Err 16 Motor temperature too high.
Wait before attempting to perform another wheel spin operation (do not
turn off the machine) (only ET66M).
Alu Err Incorrect wheel data have been input for an ALU program.
Correct the data.
Spd Hi Spin speed is too high.
Allow the wheel to decelerate and the message will automatically disap-
pear.
Rot Err Wheel has been spun in counter-clockwise direction.
Status messages
CAL [GO] Calibration spin
GO Alu Spin with ALU program selected
St Alu Static balancing selected
CCC CCC Unbalance values are greater than 999 grams for a car wheel or 1990 grams
for a truck wheel.
End Sp 1(2) End of 1st (2nd) calibration spin.
End CAL End of calibration routine (end of 3rd spin)
ALt ALt Key
has been pressed to interrupt signal acquisition.
